PAPEReFAS'IENER.

Application sied nay 11, 1910. serial No. aerien.

To all whom it may concern Be it known that I, DANIELl/V. Gaan of Cambridge, in the county of Middlesex, and State of Massachusetts, have invented certain new and useful Improvements in Paper- ,Fasteners, of which the following is a specification. n Y

This invention relatesto an implement or machine for fastening sheets of paper securely together by meansk of apart of the paper itself, and without requiring the use of additional means such asmetallic.y clips, eyelets, or the like.

My object is to provide a simple machine or device in the form of an implement which can be held and operated in one hand, and is capable in one operation, during which its moving parts or jaws close together and separate, of vcutting a tongue from the material of two or more sheets ofpaper and of drawing said tongue through the sheets.

In the accompanying drawings I have illustrated one possible embodiment of an implement designed and capable of carrying the objects of my invention into effect. y

Figure 1 represents a sectional viewof the implement in open position. Fig. 2 is a similar yview,showing the implement in closed position. Fig. 3 is a view showing the ycharacter of work performed by the imple- '-ment, the same representing two ysheets of paper after having been acted upon, showing a tongue cut from one partk of the sheets and tucked through a slit formed in an adjacent part of the sheets.y Fig. 4 is a sectional view of the fastening taken on line L -1 of Fig. 3.

The same reference characters indicate the same parts in all vthe gures.

One rconcrete form in which I have emillustration, and is hereinafter described in detail for the same purpose, but notof limitation, as I desire it to be understood that the principles ofthe invention maybe embodied in many other forms and used in many other ways than herein shown, withoutlosing its spirit or essence. In, the embodiment here illustrated, the paper fastening tool is shown as an implement similar in form to a pair of pliers, consisting of two levers, 1 and 2, pivoted together by a pintle 3, and having long arms or handle portions 4,5, and the short arms or jaws 6, 7, respec- Sipecication of Letters Patent.

tively. On the jaw 6 is formed a die 8, with which cooperates a punchQ kon the other jaw. The cutting edges on the end of the punch next to the jaw 6 have thek formV in general of the letter U, and the die is so shaped as 7. to admit the punch, embracing its U-formed edges closely,` but being open on the side of the punch opposite to the bottom of the` U, so that the punch may cut out a tongue which is integrally united at one end of the f paper, instead of being severed therefrom. To express the idea in other words it may be said that the die has a cutting edge 10, which cooperates with the edge orcorner 11 of the punch to form the bottom of the U, and thetwo side edges 12 coperate with the side edges 13 of the punch to form the legsr or sides of the U-shaped tongue. When the sheets of paper represented at 141 are laid on the jaw 6 and the jawsr are pressed together, the punch passes into the die, severing three sides of the tongue from the body of the paper and bending up the tongue about the neck whereon it is joined with the body of the paper. In orderthat this action may take place the die is formed as a slot 15 in the jaw 6, of greater length than the punch, one end and the sides of which slot form shearing edges complemental to the edges of the punch. Also carried by the jaw 7 and projecting therefrom in a direction generally parallel to the punch is a piercing device 16 which passes through the slot 15 near the opposite end thereof from the cutting edge 10 and lforms a narrow slot in the f paper. Secured to the jaw 6 is a spring guard 17 having an opening 18 to permit the punchto pass through it, and a second Aopening19 .to receive the piercer. At the end of the opening 18 the guard has a crossbar 20. The-spring guard is secured to the Alatter have passed through the paper and when the jaws are separated. The punch in passing. into the die and through the Ysheets of paper cuts the latter on ,the lines a, Z) and 1 c-shown in Fig. 3, thereby forming a tongue 22, and at the same time bends up such `jaw by vany suitable means such as a screw 21, and is separated from the jaw by a space tongue at right angles to the sheet. "At the same time the piercing device lf3-penetrates the sheets and forms a slot d therein,

jrg

` eye by `the `tongue bender,

l VTheV punch is preferably openuinfits interior andcontains one end of a tongue` bender 23,'which islpiv'oted to the jaw 'Zon a pin-24. Vhen the jaws are closed together Ythe tonguev bender 23 strikes the cross mem- Vcuttingl edge of.V which is linclined .or V- shaped, Iand the center of which is yperforated to form an opening or eye 25 of at least as 'great a width as the tongue. Thereby, when the tongue is passed through the y-it yisl acted on by the solid material at Ythe endof the piercing blade and withdrawn through the slot d with the effect shown in Figs. 3 and 4, being the same as though'the tongue had been bent back against ythe sheet and tucked throughthe In order that the tongue bender may act in the'manner described, it is so mounted as to extend from its pivot on an inclination to thepath'fin which it approaches the Vother ljaw, vso that the yportion 20 of the spring guard has a cam action upon it. Likewise the punch is open in its interior and forward side to give free play to the tongue beinrdr. j Y i i After the tongue bender has beenfdisplaced as'described, and as shown in Fig. 2, it yisj necessary to restore it to 'the normal position shownfin Fig. 1, andv for this'purpose I provide `a returning lever 26 which has'an arm27 'engaging an arm 28 of the tongue bender. This replacer has a second 'armwhi hpasses through an opening 29 in the vjaw Gf'and'the end of which Yisbent-over to make a hook 30. The engagement of this returning lever with the' jaw 6 when the Vj aws are open, causes it to be oscillated aboutV `its pivot Bl'into the position shown in lFig. 1, wherebyfits arm 27 bears on'the arm 28 ofthe tongue bender andpositions the lat- `ter. The hook 30 also acts as a stop to preventtoo wide separation of the jaws when the implementis open. l

The arms of the paper fastening 'impleyment are spring-opened andthe form ofthe f spring by which the opening is effected,

1 providingas it does greatstiffness, with sufficie'nt `resiliency to permita long life, is 'an important feature ofthe invention. The

*spring has two end portions 32 and 83 which bear against the armsor handles 4 and 5 respectively, andan intermediate portion 34 in the 'forniof' a figures. The

pintle 3 of the implement lpasses through one of the loops ofthe figurel 3, the ends 32 and 33 of Mthepspring passing to lopposite sides ofthe from'the end 82, it will be seen that it eX- tends in the'direction of the handle 4 to the pivot, being bent lback around the latter and eXtendlingf/inalmost the opposite direction, then being bent in a reverse curve and broughtaround the pintle a second time in the ksame direction of curvature as at first, until its other-end bears against 'the handle 5. The spring thus'has a sinuous form with twoof its i'loops' overlapping.
